With a full make clobber that it has to do on the source tree before it can start to compile, the OpenSolaris nightly build takes a long time:
(5) mcclung@dogstar: time nightly ./opensolaris.sh
40724.25u 7185.90s 15:02:27.12 88.4%
This is 5.11 svn_38. It's faster in an untouched OpenSolaris tree, I think, I will have to test that as well. Even with all the other stuff I compiled for /usr/local during the first build, it only took 11-12 hours.
I'm assuming we're still somewhat limited by the 650MHz CPU. I don't think it's using that much RAM, and I don't see that we're swapping (machine has 1GB of RAM.) The real limit is probably disk I/O, but I'll have to verify that.
